The Recordings can be found by going to Apps ⇒ Recordings. Through the use of the Recordings menu you will be able to upload sound files for the IVR, Time Groups, and also the default Hold Music for an extension.
To add a sound file simply click on Choose File then click Upload. After the file has been uploaded or recorded you will see it under the list of recordings. From the list you can also Play or Download the file.
Recordings can also be created by dialing *732 from your phones, then entering 1000 for the Pin number.
All of the recordings will be available in the Recordings folder. Any files recorded through the phone will show up as recordingfilename.wav
